SPECIFICATION forming part of Letters Patent No. 403,838, dated May 21, 1889.

Application filed November 28, 1888. Serial No. 292,080. (No model.)

To all whom it may concern.-

Be it known that I, MILTON HARGUS, a citizen of the United States, residing at New Edinburg, in the county of Cleveland and State of Arkansas, have invented new and useful Improvements in Log-Pullers, of which the following is a specification.

My invention relates to improvements in log-pullers to be used in connection with sawmill carriages, to draw the logs or planks from the saw; and it consists in a certain novel construction and arrangement of parts for service, fully set forth hereinafter, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a saw-mill carriage, showing the arrangement of my device thereon. Fig. 2 is a section taken transversely through the said carriage and showing the puller in elevation. Fig. 3 is a detail section on line 00 a: of Fig. 2.

Referring by letter to the drawings, A designates the carriage of the ordinary construction, having the head-blocks B B, on which rest the logs to be sawed, and C C are the standards or knees, secured movably to the said head-blocks, whereby they may be moved longitudinally of the said head-blocks. The means for operating the said standards to push them forward are not shown or described herein, as they are of the ordinary construction and form no part of this invention.

D designates a laterally-movable block, arranged on the carriage between the headblocks and provided with any approved operating device, (not shown),whereby it may be moved laterally toward either of the said headblocks, and to one side of the block D is attached my improved puller E.

G designates a lever or handle, pivoted at the lower end to the side of the block D, and H represents an arm pivoted at one end to the same pivot or bolt as the lever.

I designates the finger or hook, connected at the lower end to the free end of the arm H by the link K, and L represents a connectingbar, pivoted at oneend to the free or upper end of the hook I and at the other end to an intermediate point of the lever.

M designates a powerful leaf spring secured to the side of the block D, against the free end of which bears the under side of the arm H, and it will be seen that any pressure exerted upon the front end of the said arm will be resisted by the spring. Upwardlyextending ears N N are secured at the joint between the arm H and the link K, and the horizontal motion of the connecting-bar L is guided by the said cars.

It will be seen that if the upper end of the lever is drawn back the connecting-bar L will draw the upper end of the hook backwardly, and if a log is in position on the head-blocks the said hook will engage therein and draw it back also. Further, as the log bears against the standards when the former is drawn rearwardly by the action of the puller, the latter will also be similarly operated.

The weight of the log will prevent the hook from projecting up far above the upper edge of the block D, and consequently the connecting-bar L will press down upon the front end of the arm H and the spring will be pressed slightly down. The power of the spring,however, is sufficient to hold the hook firmly engaged in the log.

The object in connecting the free or forward end of the arm H to the lower end of the hook by the link K is obviously to enable the upper or sharpened end of the hook to move in an approximately horizontal plane.

The object of the invention is to draw the logs back after a out has been made and turn the same, and then the operating mechanism of the standards presses the said log forward to receive another out.

The device, as will be readily seen, is very simple, and may be very readily applied to any ordinary saw-mill. Further, by its use the person operating the mill may also turn the logs and thus do away with the services of aids.

The object in allowing lateral adjustment of the block D on the carriage is to enable it to be placed at the center of the length of the log supported by the carriage, so that the puller may act directly 011 the log.

Having thus described my invention, I claim-T 1. In a saw-mill, the combination,-With the carriage, having the block D, of the lever G, pivoted to the said block, the arm H, hook or finger I, connected at the lower end to the end of the arm H, and the connecting-rod L, connecting the upper end of the hook to an intermediate point of the lever, all constructed and arranged substantially as and for the purpose specified.

2. In a saw-mill, the combinatiomwith the carriage A, having the head-blocksB B, movable standards 0 C, secnred to said blocks B, and the block D between the blocks B, of the lever G, pivoted to the block D, arm 11, pivoted on the same pivot with the lever, the spring M under the free end of the said arm, finger or hook I, connected at the lower end to the free end of the arm H by the link K,

M. HARGUS.
